Hi 
Good news! we’re now letting Netlify Functions run for up to 30 seconds, for everyone. 
This has been a highly requested feature, especially since AI entered the scene so strongly. So now you can e.g. have your LLM stream back responses to the client via a serverless function, without worrying about going over the previous 10-second default.
It also means that if some of your server-rendered pages or API endpoints take a bit longer than the usual due to issues outside your control (say, a third-party API being slow), you’d experience less timeouts.
Have fun developing!
